This presentation will describe a study investigating the role of collaborative learning in enhancing student engagement in ER. While this topic has been widely documented, little attention has been paid to collaborative reading in online environment. First-year EFL college students were instructed to share their ER experiences with their peers through an LMS while working on ER. A post-course questionnaire was administered to examine the extent to which collaboration influenced their learning process. The findings suggest that collaborative learning had a positive impact on various aspects of students’ reading engagement, including goal achievement (e.g., word count and book completion), self-regulation in pacing, adherence to deadlines, and the selection of appropriate reading materials. These results indicate that incorporating collaborative elements into ER programs may enhance student motivation and accountability, particularly among reluctant readers. The study underscores the potential of collaborative learning in fostering more effective and engaging ER experiences.
